Claude's style emulation really impressed me, actually! But only after I added example paragraphs to the automated version. By default, I think the bot does an ok job describing my style from samples. But those descriptions are inevitably ambiguous. Claude won't be "restrained" or "precise" in the way I want it to be unless it sees what that looks like in practice. By using the manual-edits feature to add examples--they need to be short, so a few well-selected paragraphs--the results for me went from parody to something I use daily.
